Congrats on buying a fine revolver. I have the same experiences as MT Austin: I have two first-year L frames that I shoot a lot (one of them I bought new when they first came out) and I've never had a problem. But I also shoot mostly 158 grain rounds. If you're interested, S&W will still do the work for free under their recall program. I had one done last month, but only because I wanted a particular gun (a 686 CS-1 I just bought) factory refinished, and the recall work got S&W to pay for the shipping. Turn-arouned time was pretty quick.
Welcome to the forum.
